Been through divorce and it sucks. I was fortunate enough to negotiate that my ex not touch my retirement. Ironically one of the few things I could negotiate with the heffer.
The problem you run into here is the cost/benefit analysis. Is the divorce settlement a good one you are comfortable with? If so, is it really worth hiring a new attorney this late in the game? If not, you can try to negotiate and spend a bunch of money on a new lawyer, but just realize it could be all for nothing.
I doubt that child support is going to be reduced much if at all. As another poster stated, that’s really calculated and pretty cut and dry.
The other factor is how are things with you and your ex. Mine wanted the divorce, then decided she wanted me back, then got pissed when I rejected her and there was very little wiggle room for negotiation. If she is open to negotiation, have the talk. Be prepared to give something up in return though. If she’s not, then that’s another door that is shut.
Good luck brother and I echo the other poster that said take care of your mental health. The sad reality is financially I would have been better off going to prison then marrying my ex wife.
Fortunately for me, I married up the second time and I’m in a much better place financially then I ever was in marriage one. It takes time, but you can build back stronger than before.
